A mystery...

Code: Select all

def CofGravity::calculate ### LINE 129 ==start of class/def that is reporting the error...

def db(string)
  dir=File.dirname(__FILE__)+"/TIGtools"
  toolname="CofGravity"
  locale=Sketchup.get_locale.upcase
  path=dir+"/"+toolname+locale+".lingvo"
  if not File.exist?(path)
    return string
  else
    deBabelizer(string,path)
  end
end#db

if (Sketchup.version.split(".")[0].to_i<5)
     UI.messagebox(db("C of G: Sorry, this is Version >= 6 Tool !"))
     return nil
end#if

model=Sketchup.active_model
entities=model.active_entities

############
if Sketchup.version[0,1].to_i > 6
  model.start_operation((db("C of G")),true)### LINE 153 GIVES ERROR !!!


Can you look at the script's contents and see if it looks like this ?
Works fine on a PC for me - can't see where a Mac might trip up ?

[Jim]

Need to require 'dBabelizer' before you use it.

[TIG]

Jim

That's it ! Thanks.

Other tools requiring it were masking the fact I missed it out of the initial 'require'...

Update on it's way !!!

[driven]

that appears exactly the same,
the only thing that seems at odds is the syntax colouring for calculate shows it as a variable??
I don't know enough to know why, or where to look next

I'll send this even if the missing "require" is at fault, because I don't understand why one and not the other would be a variable....

[TIG]

Here's v1.3...
viewtopic.php?p=229404#p229404
The initial 'require' of deBabelizer was accidentally missed out, but its absence was masked by some other tools loading it anyway so most times it worked anyway...
Now it is explicitly called for in the tool...
Sorry for the confusion...

[driven]

Same error code, same syntax colouring for line 813

seems to have something to do with it...

[TIG]

Have you got the recent v1.3, with the require 'deBabelizer.rb' added ?
This should fix it ?

[TIG]

If calculate is a reserved term in Mac Ruby versus PC I'm surprised...
You can edit the file and change every 'calculate' to say 'do_calculation' and see if that helps - if so let me know asap

[driven]

Yes it's v1.3

changed to tig_calculate (lines 131, 815)

Code: Select all

Error: #<NoMethodError: undefined method `db' for CofGravity:Class>
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb:155:in `calculate'
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb:815

[TIG]

Yes it's v1.3
changed to tig_calculate (lines 131, 815)

Code: Select all

Error: #<NoMethodError: undefined method `db' for CofGravity:Class>
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb:155:in `calculate'
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb:815

You mustn't have changed them all as it's still calling 'calculate' ?
I've redone the original and v1.4 with full 'do_calculation' will be there asap...

[TIG]

Here's v1.4 viewtopic.php?p=229401#p229401 with 'calculate' replaced with 'do_calculation' to see if that fixes it - if not I have exhausted all ideas so far !!!

[chrisjk]

TIG,

Sorry for the earlier abbreviated message - I got called away from the computer.

I get the following when trying CofG (Version 1.4 here).

Ok, v1.4

sorry

[Gaieus]

...Any more ideas welcome...

Not yet, TIG - at least not anything that would be clear. I was just thinking aloud and combining my ideas. Maybe when I have already used the plugin for such things.

Thanks anyway!

[TIG]

Aaaarrrgh...
BUT as we can all see it is defining db as a method inside the particular class::def and then using it - the way it's used loads of times in other tools too... It works fine on PC so what is so special about a Mac ?
Puzzled... Any Mac scripters have any ideas ???

[driven]

it is in the db method,

I just ran composite on to groups and got this

Code: Select all

Error: #<NoMethodError: undefined method `db' for CofGravity:Class>
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb:604:in `composite'
/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb:817


[chrisjk]

Possibly something to do with the version of Ruby? Macs running Snow Leopard come with a pre-packaged version 1.8.7 of Ruby.

[TIG]

The error is with the db def method... BUT it ha been and is still working fine on PCs and it's been used in similar ways in many other tools... so why the problem here ?
To avoid having to add deBabelizer(string, lingvo_file_path) to every string in the output that needs translating I make a shortcut method def db for each tool
that alls deBabelizer and has the lingvo_file_path hardcoded into it, and works simply as db(string).
It's easy and effective in all my recent tools, so why the problem here ???
It's clear now that it wasn't the missed out 'require' or other possible clashes that were causing this... BUT why it's not working is a mystery...

Surely you can call a def inside another def though ??? even with 1.8.7 on Macs ???

[DSG2k]

I had checked for any evidence of Vista stupidity given past experience with having to look at the Virtual Store. But I've tried v. 1.4 and it works great!

Thank you so much for your incredible plugins. I'm using them for sci-fi mesh analysis and they are invaluable.

[TIG]

Seems to work fine on PC but on Mac it falls over... I WILL find a solution...

[driven]

I'll try it on an sterile Mac i.e. just on it's own, see what happens, give me five minutes

[driven]

Same error when v1.4 + debabelizer are the only rubies installed

[Dave R]

TIG,

It's not all Macs that have problems, though. It works just fine on mine. Could it be another plugin or something?

[TIG]

As I suspected
I'll sleep on it... and see how I can devise a work around in my sleep...
PC works fine - come on Mac's what's up with you !!!
Is it a particular version of Mac OS and the Ruby version that they have ???

[driven]

well, mine are
both running SU 7.1
both running OSX 10.5.8
both running Ruby version 1.8.6
MacBookPro is a fresh SU instal with just v1.4 bits
iMac is littered with rubies but very few clashes are left roaming free, it is also running rubygems, but that doesn't seem to effect any thing else in SU

both give same error

[Dave R]

Must be something wrong with my Mac, then.

[driven]

Must be something wrong with my Mac, then.

yeh, you sure it's not a PC....

[Dave R]

Very funny. I have both and I know the difference.

Here's proof that it works on my Mac.

[wind-borne]

works ok on my Mac but TIG Tools folder replaced existing one so extrusion toolbar icons disappeared. I see missing icons on Dave's screenshot also.

[chrisjk]

Most mysterious. I have tried with no other plugins or tools in the respective folders and using CofG version 1.4 I still get:-

Code: Select all
